To all 207mm t may concern Be it known that l, THOMAS DEAN, a citizen of the United States, and a resident of Indianapolis, county of Marion, and State of Indiana, have invented a certain new and useful Fasting Device; and l do hereby declare that the following' a full, clear, and enact description thereof, reference being had to the accompanyingdrawings, in which like numerals refer to like parts.

This invention relates to a machine for making flexible bookV covers and more particularly to the pasting device for the same. This invention is a divisional application of the co-pending application entitled Machine for making book covers, Serial No. 242,483, iiled June 28th, 1918, and patented Jlpril 13, 1920, No. 1,336,944.

The chief object of this invention is .to hold the covering material in position while the adhesive substance is automatically applied thereto.

The full nature of the invention will be understood from the accompanying drawings and the following description and claims Figure 1 is a top plan view of the pasting device, the same being incorporated in a cover forming machine. Fig. 2 is a vertical longitudinal sectional view of the pasting device showing the operating parts in side elevation. Fig. 3 is a vertical transverse sectional view of the pasting device, parts being broken away. Fig. 4` is an' enlarged top plan view of the adhesive applying mechanism. Fig. 5 is a sectional view'4 thereof as seen on line 5 5 of Fig. 4, with the parts in inoperative position. Fig. 6 is a similar view with the parts in the operative position. Fig. 7 is a 'sectional view of the paste reservoir, which shows the manner of operating the adhesive applying` mechanism.

A pair of endless link chains 12 extend around sprocket wheels13 and are carried by the platform 2, the endless conveyor 'being provided with suitable gripping devices with whih'the cover tis positioned be- Serial No. 344,957.

neath the pasting device to receivethe adhesive. Y i v The adhesive applying mechanism coinprises a plate 25 in the lower face of which are formed channels 26 and 2T, and in said channels is mounted `a Vclamping frame 28 and an adhesive applying frame 29 respectively, the lower face of the adhesive applying frame being preferably provided with corrugations 30 in order to obtain and apply a greater amount of the adhesive material. The clamping frame 28 is force-d downwardly by means of plungers 31 which extend upwardly through theplate 25 and are hollow at their upper ends to receive stems 32 which are attached at their upper ends to cross bars 33, said cross bars being adapted to receive `pressure to force the plungers downwardly` and move the clamping frame into engagement with the covering material.

The clamping frame 28 is normally vrreturned into the channel 26 byfa spring 34 around the upper portion of the plunger 31, the upper end of said spring pressing against the collar 35 of the plunger;` The stem 32 is slidable in the plunger 31 and is normally held in elevated position by means of the spring 36, one end of which engages the upper face of the collar 35, while the opposite end presses against the lower face of the cross bar 33. The adhesive applying frame 29 is forced downwardly by means of plungers 37, the upper ends of which are connected with thecross bar 38, the frame 29 being normally held seated in the channel 27 by springs 39 around'the plungers 37, between the plate 25 and thel cross bars 38.

The frames 28 and 29 are operated by means of rocking levers 40 which are pivoted between' their ends to standards 4l, the inner ends of said levers having curved projections 42 and 43which engage respectively with the cross bars 33and 38. These levers, when rocked upon theirpivots in one direction, force downwardly the plungers '31 and 37 `and cause the 'frames'28 and 29 to engage with the covering material 7. The

frame 28 holds the cover in position upon the movable platform 44, see Fig. 6, while the frame 29 applies the adhesive to the covering material. The movement of the plat- -form 44 is secured by suitable means illustrated Aand described in detail in thezpate'nt l hereinbefore mentioned, and reference being had thereto. The levers 40 are rocked upon their pivot pins to operate the frames 28 and 29 through the medium of stationary heads 45 and-the adjusting screws 46 carried by the outer ends of the rocking levers 40, coming in contact with the heads 45 as the plate 25 islowered.

The levers 40 are so arranged that the plunger 31 and they clamping frame 28 attached thereto will be moved into engagement with the covering material 7 before the pasting frame 29 carrying the adhesive substance is engaged with the covering material. Since the compression of the springs 36 is greater than the springs 34 and the compression of the springs 39, the frame 28 will remain in engagement with the adhesive applying material 7 until after the covering frame 29 has been disengaged therefrom, thereby preventing the covering material from being carried upwardly by the frame 29, the frame 29 leaving a quantity of adhesive material on the surface of the covering material. The movable platform 44 isy held yieldingly in position by means of springs 47 (see Fig. 2) so that the corrugated lower face of the frame 29 will not be injured by pressing too firmly against the movable platform when the frame is lowered to place the adhesive on the coverinomaterial.

eans for supplying adhesive to the corrugated face of the frame 29 is herein shown comprising a trough 48 for the reception of any suitable adhesive substance. The ends of the'trough are slidably mounted in grooves 49 formed in the frame 50. The transverse roller 51'is rotatably mounted in the trough 48 and projects above the upper edge of the trough, so that as the trough is moved back and forth between the frame 29, theJ face of the roller will engage the face of the frame and transfer a coating of adhesive material thereon. It will be understood that the endless chains 12 have a reciprocating movement across the face of the platform 2. The trough 48 is moved back and forth below the frame 29 through the medium of a latch 52, see Fig 7, which is pivoted to a part of the trough and lis' so arranged that one or the other end thereof will extend in the path of a lug 53 carried by the chain 12. When the latch is in the position shown in Fig. 7, the lug 53 will engage one end of the latch and cause the trough to travel with the chain .as the grippers are being moved for engagement with the sheet of covering material'. When the trough reaches the end of-this lateral movement, the inclined face 54 of the latch will engage the trip pin 55, so as to permit the lug to pass out'of engagement Vwith the latch and continue its travel with the' chain 12,'vwhile the troughremaiIlS .Stationary.

This operation disposes the opposite end of the latch in the path of the lug 53, so that when the reciprocating chain 12 is on its return stroke, the lug 53 will engage the latch 52 and return the trough to its initial position, the tapered face 56 engaging a trip pin 57 at the opposite end of the frame 50, thus again releasing the latch from the lug and permitting the chain to continue its travel while the trough remains stationary Any suitable means may be provided for holding the latch in its tilted position, or against swinging movement, such as a spring 58 which is carried by the trough and presses against one face of the llatch rllhe plate 25 and the frame members Vcarried thereby are lowered into engagement with thesheet of covering material 7, in order to apply adhesive substance thereto through the medium of rods 104, (see Figs. 2 and 3), the upper ends of the rods being attached to parts of the base plate 25, while the lower ends of the rods are connected to the cross bar 105'. The ends of this cross bar are provided with studs 106 which engage cam channels 107 in the cam wheels 108, suitably and rotatably mounted in the frame 1.

Means for operating the chain is herein shown in dotted lines inV Fig. 2,V and comprises a train of gears 143, 144, 145, 146 and 147, the latter gear coperating with the segmental rack 148. The segmental rack is carried by a lever 149, the lower end of which is pivoted, so that by swinging the rack in the arc of a circle, the train of gears for operating the pinions will be rotated in the opposite direction. Means for rocking the segmental rack comprises a pitman 150, one end of which is attached to the lever 149 midway its ends, the opposite end of the pitman being pivoted eccentrically upon the face of the disk 134, thus givingv the lever 149 a rocking motion when the disk 144 is rotated.
